Cole-Parmer 台式型号的pH / ORP控制器与记录仪; 110 VAC，50/60赫兹

Benchtop model pH/ORP controller with recorder; 110 VAC, 50/60 Hz

设置高，低报警0.1个pH单位（10毫伏）内一个电极输入。当pH或ORP水平超过预设的限制，前面板的信号灯亮起。然后，控制器激活泵，电磁阀或其他以两个110 VAC网点的连接的工具台式机型或有线的两个110伏交流供电继电器壁挂型号。定时报警电路切断电源输出，如果pH或ORP水平不回预设范围内选择的时间量程（从0到10分钟可调）。

镜子支持6寸模拟量表具有的pH值范围0到14（±700毫伏）规模扩大是pH值1.4（140毫伏）量程。一台记录仪提供了一个永久性记录的pH值（0〜14）;记录纸（包括）持续三十日。基准型号是可以带或不带内置的记录仪。所有的壁挂式机型包括一个内置记录仪。订购无温度补偿的pH值，ORP电极与BNC接头。

台式机型包括单电极输入，您可选择带或不带内置记录仪。

Set high and low alarms to within 0.1 pH unit (10 mV) for one electrode input. When pH or ORP levels exceed preset limits, front-panel signal lights up. Controller then activates pumps, solenoid valves, or other instruments connected to the two 110 VAC outlets on the bench models or wired to the two 110 VAC powered relays on the wall-mount models. Timed alarm circuit shuts off power output if pH or ORP levels do not return to preset limits within the chosen time span (adjustable from 0 to 10 minutes).

Mirror-backed six-inch analog scale has a range of pH 0 to 14 (±700 mV); expanded scale is pH 1.4 (140 mV) span. A recorder provides a permanent record of pH (0 to 14); chart paper (included) lasts thirty days. Bench model is available with or without built-in recorder. All wall-mount models include a built-in recorder. Order non-temperature compensated pH and ORP electrodes with BNC connectors .

Bench models include a single electrode input and allow you the option of models with or without built-in recorder.
